Ok,

Well I just blundered flashing my HD 6750 to a 5750 and what did I do I never selected 5750 or 5770 but instead I chose 6850 and I don't know how or why did I choose that device , so now i am stuck with a card which does work but windows or atiflash cannot detect the card.

Got to wait for the PCI card from a friend so that I could reflash the 6750 as using the onboard 4250 does not work for reflashing.

I am also on the lookout for a card which would work both in SL and Win 7. My budget targets me towards 7750 as the GT640 does fall under the same price range but the reviews aren't so good.

on my HD6770, I have 3 chips with 8-pin, I took one of above

Ok I will try it , if it gets bricked totally than I have to get my hands on a new card.

But one thing I had seen is that the first I time I flashed the bios new Device id to 5750 and it flash perfectly ,but after rebooting it was still showing me a 6700 series card in win 7, and when I load SL it tells me it a 5700 series card. I know that the 6750 are a rebranded bunch, funny.

Now my Sapphire HD 6750 is a 2 GB card and nowhere on techpower do I see any 5700 series or for that matter even a Sapphire 6750 with 2 GB.

you can tell me how you did it ?

well I shorted pin 4 & 5 on a different motherboard which I have as a standby but I could still not get the card to be detected by atiflash (booted using USB / Dos) then I wanted to check if the card still gives a display , well the display had stopped , so I think its bricked now and need to send for replacement , don't know if they shall else I will go for 6850.
